ذِكْرُ الزَّجْرِ عَنْ صَلَاةِ الْمَرْءِ النَّافِلَةَ إِذَا غَلَبَتْهُ عَيْنَاهُ مَخَافَةَ أَنْ يَقُولَ مَا لَا يَعْلَمُ
[Machine] The Messenger of Allah (may peace be upon him) entered the mosque and saw a rope stretched between two pillars, so he asked "What is this?". They said, "It is for so-and-so woman who prays, and when she gets tired, she holds on to it." The Messenger of Allah (may peace be upon him) said, "Let her make her prayer as long as she is focused and attentive. But if she fears that she might be overwhelmed, then let her shorten it."
أَنَّ رَسُولَ اللَّهِ ﷺ دَخَلَ الْمَسْجِدَ فَرَأَى حَبْلًا مَمْدُودًا بَيْنَ سَارِيَتَيْنِ فَقَالَ «مَا هَذَا؟ » قَالُوا فُلَانَةٌ تُصَلِّي فَإِذَا أَعْيَتْ تَعَلَّقَتْ بِهِ فَقَالَ رَسُولُ اللَّهِ ﷺ «لِتُصَلِّ مَا عَقَلَتْ فَإِذَا خَشِيَتْ أَنْ تُغْلَبَ فَلْتَنَمْ»
